have no idea if low lvl minigames happen.
ce often has people farming and people ganking them, usualy after a while russians show up in a zerg.
about duels its semi popular to use khemi renown arena for it.
but some people prefer to do duels in border to kush.
that pretty much all the world pvp there is on crom.
also the festival was decently populated, and people would always group up in minizergs fighting each other was fun, although sometimes frustrating due to russian bigger numbers at times.
there seems to be some tricks to getting extra pvp xp on festival namely win a few events for pvp xp buff then use potion+food with pxp xp enhancer and only then consume as many quest reward skulls and other weird new pvp items, you can get massive pvp xp like that have guildy who made like 60% from pvp6 directly to pvp7.
so you have an idea here is a small video a guildie of mine did of us doing some open world pvp at festival with guild members+some randoms

minigames are same crap as in fury, main thing is general atitude in minigames is a bit worse on crom less teamplay, and 2 criticaly hated pro afk'ers.
some guild organize inguild small premades vs friends, not often.
main thing is on crom you have full access to all pve content and most pvp content except the daily pvp quests, wich hopely in near future with revamped pvp instances for 6 festival locations will include access on crom to pvp daily quests.
best for you if moving to crom is have a look at guild hall and find a guild who you think has right profile for you to fit in, most guilds are recruiting and especialy on summer time they have more places in main raid forces due to slack time.
